| They should open in any case but you can remove the data fork which contains the preview image (and other Mac specific info) by using Grim Ripper. It may be the cause of your problem. http://www.macupdate.com/info.php/id/9105 |

| You may have saved your jpgs as CMYK since you're scanning them and that might be the default color space. Make sure you check your jpgs for RGB colorspace. Jpgs should open fine on both macs and pcs without any fiddling.

| well, if you are saving them as .jpeg, and not .jpg, then that might be what is throwing off the pcs. they really don't do well with file extentions that are more than 3 letters/numbers long, or are missing.

| Good idea that. Your computer won't recognize the file if you use .jpeg instead of .jpg.

| Well, I've been able to open .jpeg files and .jpg files in Windows XP. I'm leaning more to the fact that it was saved as a CMYK and not as RGB. The same thing happened to my father who was working on a letterhead graphic on Illustrator. He ended up exporting it to .jpg but it was using CMYK instead of RGB. The second I exported it again in RGB, everything started working properly.

| One thought is that if you are hiding the file extension on the Mac, sometimes it send with out a file extension to a PC. And the PC will freak out. Make sure when you open it on the PC that it has the correct file extension on it, it may just be missing it. |
